DVD-9 (Dual Layer)

Peter Moore · April 20th, 2003, 12:27 PM

Ok that makes sense. Except for the super-high bitrate disks like Lord of the Rings, a two hour movie should fit on one disk - the extras are what pushes it into dual layer, I guess.

By the way, someone said it was a legal backup. Sure it's legal for you to do it, but the people who make that software are opening themselves up for liability just like DeCSS. So don't be surprised if that software disappears sometime.

A good VBR multi-pass hardware encoder can do 2 hours to one disc. But most software encoders have a noticeable loss of quality with programs over 90 minutes. There are exception, of course, but you'll probably see a quality loss if you go 2 hours.

Hi
For Your information, http://www.mrbass.org/dvdshrink/rmat has the program DVDshrink, that will compress, up to a 9GB dvd, to a single dvd-r, gives up to 8 levels of compression, keeping everything or You can just do the main movie.
The disc will then "burn" using Record Now Max, or any prog that will burn AC3 audio.
It takes about 32 minutes to encode on a 2000xp processor.Then whatever speed Your burner takes to record, quality is very good I.M.O.

Hope this helps.

Best Wishes.

Peter.

The Adobe Encore information does mention dual-layer and DLT, but it does not specifically say that the product will author a DVD-9. My experience so far is that if a product does author a DVD-9, the vendor specifically says so. If the product doesn't, the information is usually vague.

Adobe's information is vague.

I've tried to confirm this one way or the other but haven't been able to yet. Does anyone else know for sure? DVD-9 at a $500 price point is huge news if it's true.
